Thanks for your photos. Based on what I see here, you have either our S380-34 or S385-34 , depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.

Sure, if you refer to the chart on the S380-34 store page then you have two options: either the 3340, which carries 23 through 28 pounds, or the 3350, which carries 28 through 32 pounds.

Since your old stamp is 33-5, I personally would go with the 3350. They're technically the same stamp. Ultimately, though, the choice is yours.
